Hello,
I have a 92 300E Sportline. Recently during a hot day I was sitting in a drive thru window line and air stopped blowing out of the vents. I could tell that cold air was still leaking out of the vents, it just wasnt being pushed out. This has'nt happened before and it didnt sputter or anything, it just stopped. I checked the push button unit for volage output, all seemed well. Also I can hear it open/close flaps when it is used, so I know that the push button unit is working. I think that narrows it down to the blower motor and i've heard something about a relay that controls the blower motor. How would i go about figuring out what i need to replace? Thanks alot for your time!
